Description
The board schema accepts material="flex", while the Circuit JSON contract and documentation allow only fr4 and fr1.
Expected: align the schema/output with the Circuit JSON contract.
Actual: a pcb_board is emitted with material: "flex".

Research direction
Start with the core repro PR #3096 and the standalone repro to trace where pcb_board material is accepted and emitted. Compare that behavior with the Circuit JSON contract and documentation. Done means material="flex" is no longer accepted or emitted, while fr4 and fr1 remain supported.
